Respiration Monitor Operating Instructions

1. Introduction: These Operating Instructions contain important information on using and caring for your Respiration Monitor. It is important to become completely familiar with all the instrument’s features so please take time to read and understand the contents of these operating instructions, particularly the Warnings and Cautions, before use. The Respiration Monitor should only be used under the direction of a suitably qualified clinician. It is important that the Monitor is used correctly, that the alarm is tested before each use and that the battery levels are checked frequently (at least daily). The supervising clinician should ensure that the Monitor is fit for the intended purpose and that it is suitable for use on each individual patient. The Respiration Monitor is used to continuously monitor the respiration of infants up to the age of 18 months. The Monitor will give audio and visual alarms if the infant stops breathing for more than a user-selected time. The respiration signal is picked up by a disposable pneumatic sensor which is attached to the infant’s abdomen. During breathing, expansion of the abdominal wall displaces a small amount of air in the sensor which is transmitted through an integral tube to the monitor. Each breath is detected by the monitor and triggers visual indication and an audible click if enabled. The Respiration Monitor only gives an indication of a potential apnoea event and cannot prevent it. The user must ensure all reasonable precautions and actions are taken.

2. Indications for Use: The Respiration Monitor is intended for use on infants up to the age of 18 months. It is designed to detect cessation of respiration where movement of the abdominal wall has stopped, as an indication of a potential apnoea event. It is the responsibility of the supervising clinician to determine if the monitor is appropriate for each individual patient and their medical condition.

3. Contraindications: The Respiration Monitor is not suitable for use on infants over the age of 18 months or where apnoea might not result in absence of movement of the abdominal wall. It is not suitable for use in situations where a member of staff is not able to hear the alarm at all times.

4. Warnings & Cautions: Warnings in these operating instructions advise of dangerous conditions that could lead to death of, or serious injury to, the user or the patient if the instructions are not followed in full. Cautions in these operating instructions advise of dangerous conditions that can occur and cause serious damage to the Monitor if the instructions are not followed in full.

WARNINGS & CAUTIONS: It is important to inspect the Monitor for any sign of damage when first received and before each use. If there is any sign of damage then pass it to an approved, qualified technician or return it to Delta Medical International or your local supplier. A qualified clinician must ensure that the functions and performance of the Monitor are fit for the intended purpose and appropriate for the individual patient.

Respiration Monitor Operating Instructions

The Monitor gives an indication of a potential apnoea event but cannot prevent or treat it; the user must take the appropriate action if the Monitor indicates an alarm. Only the approved sensor type should be used with the Monitor; failure to observe this may result in malfunction, failure to detect an apnoea event and damage to the unit. The Monitor should only be used by staff who have been fully trained and have acknowledged that they are competent in its function and operation. The Monitor is not suitable for use on patients over the age of 18 months or who are fitted with a cardiac pacemaker and must be removed before using a defibrillator. The sensor tubing must be routed carefully so there is no risk that the patient could become entangled or strangulated. The Monitor should only be used outside the hospital environment under the direction of a suitably qualified clinician and under their clinical supervision. The Monitor must not be covered by bedding or other objects that could impair the audible or visible alarms; the carer must remain within visible or audible range of the Monitor so that alarms will be observed. The user should check for any sign of malfunction regularly during use. The Monitor must not be placed where it could be accidently switched off, such as by young children or visitors, or where its operation could be compromised by positioning, such as in a confined space. Before each use ensure that the sensor is placed and secured correctly and check that the Monitor is functioning correctly, including respiration detection and alarm function. Excessive movement of the Monitor when in use may adversely affect its performance; during transport ensure that it is positioned or secured appropriately. It is important to check regularly (at least daily) during use that the batteries are not low; if low battery is indicated, or in case of doubt, fit new batteries. Only fit specified battery type. The Monitor must not be used in the presence of flammable anaesthetic gases, in oxygen enriched atmospheres or in an MRI scanner or its vicinity. If the Monitor is exposed to a significant liquid spillage then it should be wiped dry and passed to a suitably qualified technician for checking before further use. The sensor is for single patient use only and should be changed after a maximum of 7 days’ use. The screwdriver and batteries supplied with this product could be a choking hazard for small children. Take suitable precautions and if sending the product outside the hospital consider whether it is necessary to remove the screwdriver. Check that when the Monitor is turned on it does not interfere with any life support or vital signs monitoring equipment. Refer all service and repairs to a suitably qualified engineer or technician; no unauthorised modifications to the Monitor should be made. Do not autoclave, steam sterilise, ETO sterilise, immerse in fluids or expose the Monitor to high temperatures, in excess of 45°C. Place the monitor where it is not at risk of falling or being knocked or at risk that the sensor tubing could be trapped or kinked; do not lift the Monitor by the sensor tubing. Remove the sensor by pulling the tabs of the connector, do not pull on the tubing as this may damage the sensor. Do not touch the patient at the same time as touching the open battery compartment.

8. Operating the Monitor: Inspect the Monitor before each use and if there is any sign of damage then pass to a qualified technician or your supplier for checking. Check that the battery level is not low before each use and regularly (at least daily) when monitoring a patient. 8.1 Attaching the Respiration Sensor: The respiration sensor connector should be inserted firmly into the input socket located on the bottom face of the Monitor. Ensure the sensor connector is pushed fully in and is securely held in the socket. The clinician should decide the most suitable location for the sensor placement; typically this might be on the abdomen, just below the navel and slightly to one side. It is important that the sensor is placed where there is clear movement with each breath and as little movement as possible due to other factors. Clean and dry the infant’s abdomen and then attach the sensor pad using hypoallergenic tape; it is suggested that tape approximately 50mm wide and 100mm long is used. Other sensor fixation methods may be used according to local protocols. Ensure the sensor is attached so that the patient cannot become inadvertently entangled or strangulated by the tubing; it is suggested that the sensor is fixed so the tubing runs down between the patient’s legs, so it is away from the head, neck and hands. Ensure that the tape is not stretched too tightly over the sensor as undue compression of the sensor may affect its efficacy. Only approved respiration sensors should be used; they are for single patient use and should be used only on one patient. Sensors should be used for a maximum of 7 days after which they should be replaced. 8.2 Turning the Monitor On / Off: Turn on the Monitor by pressing the Power On/Off button and the Power On indicator will illuminate green. If the Power On indicator flashes yellow then this is indicating that the batteries are low and need replacing. When the power-up sequence is complete one of the Alarm Delay indicators will also illuminate, corresponding to the delay in use before the unit was last turned off. The Respiration Indicator will flash and the sounder will beep after each breath. The sounder can be silenced as described later if not required. To turn the unit off, press and hold the Power On/Off button for at least 2 seconds and then release it. The Power On indicator will extinguish to show power is off. Turn the Monitor off when not in use to preserve the batteries. 8.3 Function Tests: Before commencing respiration monitoring it is important to check that the alarm is functioning correctly. To test the alarm disconnect the sensor from the input socket and ensure that the visible and audible alarms both activate after the set Alarm Delay. Once correct alarm function is verified reconnect the sensor. It is also important to check that the unit is correctly detecting respiration. Observe the Respiration Indicator and check that it illuminates for each breath the patient takes and only for each breath. Check that the batteries are not low by observing the Power On indicator; if it is flashing yellow then the batteries should be replaced before commencing monitoring and the function tests should then be repeated.

Respiration Monitor Operating Instructions

8.4 Setting Alarm Delay: The responsible clinician should determine for each individual patient how long without breathing represents a potential apnoea event; this is the Alarm Delay. When the appropriate Alarm Delay has been decided this should be set on the Monitor by pressing the Increase Delay and Decrease Delay buttons as appropriate until the Alarm Delay Indicator beside the required delay period is illuminated. Buttons must be pressed for 2 seconds to avoid inadvertent changes. 8.5 Turning Respiration Sounder On / Off: The Monitor has a sounder that will emit a beep on each of the patient’s inspired breaths. This defaults to “On” each time the unit is powered up, but can be silenced by pressing the Sounder On/Off button. When the sounder is Off then pressing the button will turn it back On again. The Sounder indicator will be illuminated when the sounder is Off and not illuminated when the sounder is On. The Respiration indicator will continue to flash on each inspired breath even if the sounder is set to “Off”. 8.6 Apnoea Alarm: When the monitor has not detected respiration for a period that exceeds the Alarm Delay period set by the user it will generate an alarm. This will cause the Apnoea Alarm indicator to flash and the sounder to emit an audible alarm. If respiration recommences then the audible alarm will cease but the indicator will continue to flash until the Alarm Cancel button is pressed. The Apnoea Alarm is designed to indicate cessation of respiration, however it remains the responsibility of the user to take the necessary action in caring for the patient. The Respiration Monitor should not be considered as an alternative to applying the appropriate clinical attention and care for each individual patient. 8.7 Alarm Silence / Cancel: When the apnoea alarm sounds it can be silenced by pressing the Alarm Cancel button. This will silence the audible alarm for a period of one minute. After the silence period the alarm will sound again unless the Monitor has detected that respiration has recommenced.

9. Care & Maintenance: The Monitor requires very little maintenance other than routine checks for damage or malfunction and cleaning. The care and maintenance recommendations are shown below. 9.1 Cleaning & Disinfection: The Monitor should be cleaned in accordance with local infection control procedures and protocols, taking into account the information below. Disconnect from patient before cleaning. In general the Monitor should be cleaned using a soft cloth which is moistened with disinfectant solution, but not saturated with the cleaning fluid, or with appropriate disinfectant wipes. It is important to check that any cleaning products used are suitable for the purpose and not designed for cleaning other types of surface. Do not autoclave, steam sterilise, ETO sterilise, immerse in fluids or expose the Monitor to high temperatures, in excess of 45°C. The respiration sensor is for single patient use only and does not therefore need cleaning. If the sensor is soiled or not clean then it should be disposed of and a new sensor used. Model: RM15

9.2 Routine Maintenance: When carrying out any maintenance the monitor should not be connected to a patient. The Monitor should be checked for any sign of damage or contamination before each use. If there is any sign of damage then take the unit out of service and refer to a qualified technician. If there is any sign of contamination then clean the unit thoroughly using approved protocols. The battery level should be checked before each use and if the indicator shows batteries are low then replace them with new ones. If the Monitor is not going to be used for an extended period then the batteries should be removed to avoid risk of degradation. On an annual basis the monitor should be checked for damage and correct function by a qualified technician. This should include opening the battery compartment and checking for damage to the retaining screw and for any sign of contamination due to battery failure. 9.3 Service & Repair: Service and repairs must only be carried out by a suitably qualified engineer or technician. The monitor case must not be opened when the monitor is connected to a patient. Delta Medical International will make available the necessary service information to qualified personnel, on request.

10. Battery Status & Replacement: When the batteries are low the Power On indicator will flash yellow intermittently when the unit is turned on. A brief, intermittent audible beep will also sound, approximately every 30 seconds. If batteries are low they should be replaced promptly. To access the battery compartment release the cover plate retaining screw using a suitable screwdriver. Do not use an incorrect screwdriver type or size as this may damage the screw-head. When the screw is released lift the cover off using the small tab adjacent to the screw. Remove the batteries and replace with new ones, which must be of the type specified (AA Alkaline type only). Note the polarity which is marked inside the battery compartment and ensure batteries are the correct way round. Insert each battery by pushing the negative polarity end of the battery to compress the spring and then slide the positive polarity end down until it is fully inserted into the compartment. Dispose of old batteries according to local regulations. Replace the battery compartment cover by holding at an angle with the end away from the screw downwards and inserting the retaining tab into the slot provided. When the tab is inserted fully push down the screw end of the cover, hold it in place and tighten the retaining screw using the correct screwdriver. Always replace the battery compartment cover.

11. Fault Finding: If the Monitor does not function as described or as expected please check the following fault finding table. Follow each step of the Corrective Action in order and if any step does not correct the fault move to the next step. If the Corrective Actions do not fix the problem please refer to a qualified technician or return the unit to Delta Medical International or your local distributor for repair.
